URI oceanographer studies seasonal changes in coastal ’jet’ south of Block Island

University of Rhode Island Graduate School of Oceanography physical oceanographer David Ullman and University of Connecticut physical oceanographer Dan Codiga have studied the processes giving rise to a coastal current jet that forms in the Atlantic Ocean south of Block Island. Although the commonly accepted scientific view has been that the flow along the southern New England continental shelf is steady on seasonal timescales, recent collection and analysis of long-term current records as part of a

Meteorite from Oman Records Its Lunar Launch Site and Detailed History

Scientists have pinpointed the source of a meteorite from the moon for the first time. Their unique meteorite records four separate lunar impacts.

They are the first to precisely date Mare Imbrium, the youngest of the large meteorite craters on the moon. That date, 3.9 billion years ago, is a new key date for lunar and even terrestrial stratigraphy, the scientists say, because life on Earth would have evolved only after heavy meteorite bombardment ended.

New Screening Technique Uncovers Gene-Drug Interactions

Scientists have developed a new screening technique to help them look for genes that change patients’ responses to cancer drugs and other medications.

Researchers looking for such connections confront an enormous hunting ground of approximately 33,000 human genes. Normally their only options for mounting a search in such a vast field are either to rely on anecdotal reports of dramatically altered patient reactions, or to conduct extensive surveys of the genes for all the proteins kn

Enhancing Metro Security with Intelligent Surveillance Tools

Sophisticated tools used to survey and monitor passenger flows through busy metro stations may result in unmanageable data loads. ADVISOR’s decision support tools reduce the workload of operators and increase the utility of the data output.

ADVISOR, which stands for Annotated Digital Video for Intelligent Surveillance and Optimised Retrieval, “is a significant aid to the operators in charge of metro security,” says project coordinator Michael Naylor. “The principal of the [ADVISO

Heartless Worms Offer Insights Into Cardiac Arrhythmias

C. elegans model helps identify protein linked to long QT syndrome – Could help lead to development of drugs that don’t cause calcium channel block

The worm C. elegans seems an unlikely candidate for studies related to cardiac arrhythmias. After all, the microscopic organism doesn’t even have a heart.

That fact did not deter Christina I. Petersen, Ph.D., research assistant professor of Anesthesiology at Vanderbilt University Medical Center. Petersen and colleagues, includ

Unlocking Tick Genes to Combat Disease and Bioterrorism

Ticks as small as a freckle can transmit a number of illnesses for which there is no vaccine and, in some cases, no cure. These creatures even could become bioterrorism weapons.

To find new ways to control the tiny animals and halt the spread of the pathogens they carry, Purdue University researchers and colleagues from the University of Connecticut Health Center, the University of Notre Dame and Massachusetts Institute of Technology are undertaking the job of unraveling the genetic

UK Scientist Bets on Gravitational Waves Discovery Odds

At the Institute of Physics conference Photon 04 yesterday, Professor Jim Hough, one of the UK’s leading scientists, revealed that he thinks high street bookmakers are crazy to be offering odds of 100-1 on whether Gravitational Waves (wrinkles in relativity) will be discovered before 2010. He has placed a personal bet of £25 – the maximum Ladbrokes allowed him to stake. The available odds were quickly cut from an initial offering of 500-1.

Innovative Approach Targets Glioblastoma Cells Using Apoptosis

By mimicking a molecular switch that triggers cell death, researchers have killed cells grown in the laboratory from one of the most resilient and aggressive cancers – a virulent brain cancer known as glioblastoma. The new approach to tricking the cell-death machinery could be applied to a wide range of cancers where this pathway, known as apoptosis, has been inactivated.

UK Scientists Discover New Ring and Objects Around Saturn

The joint NASA/ESA/ASI Cassini-Huygens mission is continuing to provide a fascinating insight into the Saturn system. The latest detection of one small body, possibly two, orbiting in the planet’s contorted F ring region and a ring of new material associated with Saturn’s moon Atlas, has been made by a team of UK scientists.

A small object was discovered moving near the outside edge of the F ring, interior to the orbit of Saturn’s moon Pandora. The object was first seen by Professor C

Distinctive Signature Found for Metastatic Prostate Cancer

Howard Hughes Medical Institute researchers have identified a telltale change in cellular machinery that could help clinicians predict whether prostate cancers are likely to spread or remain relatively harmless in the prostate.

The researchers found that a cellular signaling molecule called Hedgehog, which drives normal development and regeneration of prostate tissue, is greatly activated in prostate cancers. This elevated activity distinguishes dangerous metastatic cancers – those t

£4.5 Million Grant Boosts Cost-Effective Solar Power Innovation

Whether the search for alternative energy sources is driven by our concern about global fossil fuel supplies or over the atmospheric effects of burning of fossil fuels, the government has laid out its aim to cut carbon dioxide emissions by 60% of 1990 levels by 2050, and aims to over- achieve its goal of sourcing 10% of energy from renewables by 2010.

In a significant step to achieve these targets, an enormous £4.5 million award has been made under the UK SuperGen programme to drive

UAF Scientists Uncover New Marine Habitat Near Knight Island

While researchers in Alaska this summer used high-tech submersibles and huge ships to plumb the deep-ocean depths in search of new species, a team of scuba diving scientists working from an Alaska fishing boat has discovered an entirely new marine habitat just a stone’s throw from shore.

The discovery in June of a single bed of rhodoliths, colorful marine algae that resemble coral, was made near Knight Island in Prince William Sound by scientists at the University of Alaska Fai

UK Students Use Telescopes to Track Hazardous Asteroids

Tracking newly discovered asteroids and comets to identify their orbits is the work of a small number of observatories. Yet UK students, using the Faulkes Telescope North – a remotely operated research quality telescope dedicated for educational use – will now be swelling these ranks. The students have taken such accurate data of a number of asteroids that the telescope has been awarded an observatory code and can now submit official data to the international body that monitors asteroids and comets,

Microbial Life Discovered in Atacama Desert’s Harsh Soils

A place so barren that NASA uses it as a model for the Martian environment, Chile’s Atacama desert gets rain maybe once a decade. In 2003, scientists reported that the driest Atacama soils were sterile.

Not so, reports a team of Arizona scientists. Bleak though it may be, microbial life lurks beneath the arid surface of the Atacama’s absolute desert. “We found life, we can culture it, and we can extract and look at its DNA,” said Raina Maier, a professor of soil, water a

Bacteria and Nematodes: Eco-Friendly Solutions for Pest Control

In a world where 842 million people suffer from chronic hunger, insect pests consume 20-30 percent of world food crops. Chemical pesticides are increasingly expensive, ineffective and environmentally aggressive, killing beneficial insects and, when transmitted through the food chain, moving in unwanted directions.

The search for eco-friendly bio-insecticides has focused mainly on developing transgenic crops that express natural protein toxins. The most successful, by far, are crops

New Agents Show Promise Against Leishmaniasis Challenges

Parasitic diseases, especially leishmaniases and trypanosomiases, kill hundreds of thousands of people every year in the world, mainly in the countries of the South. The most severe form of leishmaniosis (kala-azar, the visceral form), induced by Leishmania donovani and L. infantum, affects about 500 000 people per year and proves fatal if no treatment is given.

Although drugs do exist for treating these diseases, they are not always effective, owing to the appearance of r

Examination of internal ’wiring’ of yeast, worm, and fly reveals conserved circuits

Researchers in California, Israel, and Germany have compared three distantly related species – baker’s yeast, a worm, and the fruit fly – and reported that protein “wiring” connections in one species are often conserved in all three. This first-of-its-kind analysis of three higher level organisms published in the February 8 issue of Proceedings of the National Academy of Sciences supports both the concept of a basic wiring diagram for all eukaryotic cells, and the idea that more selective pha

New Quinolines Show Promise Against Sandfly Fever

Leishmaniases and trypanosomiases are parasitic diseases which kill several thousands of people per year, mainly in developing countries. The effectiveness of existing treatments is being called into question owing to their toxicity and the emergence of resistance. A family of alkaloids, the quinolines, could be a worthwhile new therapeutic line to follow. Following on from the discovery of anti-leishmaniasis activity in natural quinolines, a research team of IRD, Pasteur Institute and CNRS sci
